Merged with mserve/master: Improved garbage.php; Added example4.html; Changed handling of settings

- changed worker: allowing direct message to set options, also timeouts and pingcounts
- examples changed with new set message

New example using justgage.js for nice displays, and Google Fonts for more awesomeness of this tool
Changed garbage.php, now enforcing download (good for comparisons of measured speed vs. raw download speed) and disabling php buffering stuff
